In a code language, 'he is tall' is coded as 'lu ma na', 'Giraffe is tall' is coded as 'na pa ma'. What is the code for the word 'Giraffe'?

Let's compare the sentences and their codes to find common elements:
'he is tall' → 'lu ma na'

'Giraffe is tall' → 'na pa ma'

The words 'is' and 'tall' are common to both sentences, and their corresponding codes 'ma' and 'na' are also common to both code groups.
Removing these common elements leaves:

Word: 'Giraffe'

Code: 'pa'

Thus, the code for 'Giraffe' is 'pa'.
